T- all whom it may concern:

Be it known that we, HERMANN EISERT, re-

I siding at Baltimore, and ROBERT BARNARD TALOOTT, residing at GarrettPark, inlthe county of Montgomery and State of Maryland, citizens of theUnited States, have invented certain new and useful Improvements inRadiator-Valves; and we do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention is directed to valves for steam radiators, and relatesparticularly to that class of radiator valves in which provision is madefor controlling the circulation of steam in the radiator independent ofthe general circulation, whereby any radiator may be cutoff withoutdestroying the circulation in the pipes connecting that radiator withthe main pipe system.

An object of our invention is to produce a valve of this character whichis capable of performing all of. the functions of the two valves usuallyattached to a radiator, which common arrangement results frequently-in.disorders in the circulation of steam, and also in annoying noises inthe radiator, caused by one or the other of the two valves beingaccidentally or negligently left open or closed as the case may be.

, valves for connection with differing or unusual arrangements of steampipes.

Another object of our invention is to provide in such a valveinterchangeable joints,

one for the supply and the other for the return pipe, whereby therelative location of said pipes may be changed at will, the joint forthe supply pipe extending within the valve body to prevent, when thevalve is in a certain position, the entrance into said supply pipe ofthe water of condensation.

Another object of our invention is the production of an improved valveproper, by which all tendency to disorder and leakage is overcome.

The nature of our invention'will appear from a reading of the subjoineddescription when taken in connection with the accompanying drawingswhich form a part of this specification, and in which-- Figure 1 is anelevation of our improvedvalve. Fig. 2, is a vertical central section.Fig. 3, is a horizontal section on line mm of Fig. 2 looking toward theradiator connection, showinga connection with vertical steam pipes; Fig.4, a similar view showing a connection with horizontal steam pipes; Fig.5, a similar view showing a connection with horizontal steam pipesarranged in a direction opposite to the pipes in Fig. 4-; Fig. 6, asimilar view showing a connection with inclined steam pipes; Fig. 7, aview partly in section of a union joint for the supply steam pipe; Fig.8, a similar view of a union joint for the return pipe. Fig. 9 is aperspective view of a plate for connecting the valve proper and stem.

Like letters of reference denote like parts throughout the figures ofthe drawings.

Referring to the said drawings by letter, A denotes the body of thevalve which is provided with three openings, one of which, I), leads tothe radiator, another, 0, to the steam o supply pipe, and another, at,to the return pipe. At the opening b thebody is provided with anintegral, externally threaded flange a havinga ground-joint forconnection with a union e by which the valve is secured to the 5radiator, or if desired this opening may be internally threaded forattachment to the radiator by nipple connection. The openings 0,

ternally threaded for a portion of the length for connection with thesteam supply pipe g. The tube is threaded externally at f for engagementwith the threaded openings 0 or d, and atf 2 the tube is made polygonalto permit of the joint being turned by a wrench. Beyond the threads f isan extension f which, when the joint is in place, projects into thevalve body a distance sufficient to form a barrier against the water ofcondensation which would otherwise have a tendency to flow into saidsteam pipe when the latter is arranged vertically as shown in Fig. 3.

h is the reducer joint, for the return pipe 11, the interior of which isthreaded at h for a portion of its length for connection with said pipe,and its exterior is threaded at 72. for connection with the threadedopenings (1 or 0. At it the joint is made polygonal in shape also for awrench hold. The openings 0 and d are of the same diameter and pitch ofthread, as are also the threaded portions f and 77.2 of the reducerjoints, thereby enabling said joints to beinterchanged at will for apurpose which we will now explain.

In the setting up of steam heating apparatus, the steam supply andreturn pipes are led into a room in various ways, as for instance,vertically through the floor, or the steam from a ceiling and the returnthrough the floor or wall, or through a wall horizontally, and in somecases at an incline; and said pipes are also frequently connected to theright as well as to the left end of a radiator, necessitating thereforthe production of right and left valves, and a specially constructedvalve for each modification of the arrangement of pipes.

As before stated, our improved valve may without altering itsconstruction, be employed for any arrangement of pipes, and may also beconnected to either end of a radiator. The connection between the valveand radia tor is such that the valve may be turned to any angle withsaid connection as a pivot, the various positions of said valve beingshown in Figs. 3 to 6 inclusive. In the arrangement in Fig. 3, the pipesare shown vertical andin this position of the valve the extension foperates as before stated to prevent the entrance of condensed steaminto the steam supply pipe. I

In a horizontal arrangement of the pipes, the steam pipe is alwayslocated above the return pipe, and in Fig. 4 the reducer joint f isinserted in the upper opening. In the event of the pipes coming from theside opposite that shown in said figure, or connection being made at theopposite end of the radiator, the reducer joints are interchanged andthe arrangement is then as shown in Fig. 5.

Fig. 6 shows an arrangement of inclined pipes which may be changed toany angle, the valve as before stated being capable of being turned andused in any position in the lower half of a circle.

Y Referring now to Figs. 7 and 8, j, 70, denote respectively unionjoints for the steam sup- .ply pipe and the return pipe, when such aconnection is found desirable. These unions are of common type with theexception that they are interchangeable, and the union j is formed withan extension j which performs the same function as the extension f whenconnection is made between said joints and vertical pipes leadingthrough the floor.

Referring now to the valve proper, Z denotes said valve, and m is thestem which latter is passed through the top of the body and terminatesin a hand-wheel n. In the top of the body is a threaded opening ofcomparatively large diameter, which is internally threaded to receivethe cap 0 which is provided centrally with a sleeve 0 which receives thestem. The upper end of this sleeve is externally threaded to receive astuffing box 0 which surrounds the stem as shown. The valve stem isprovided near its lower end with an integral collar m, and m is areduced end having a threaded aperture m and a groove or any othersuitable depression on. The valve proper consists of a disk having acentral aperture Z to receive the end m of the stem, and p'is a securingplate of larger diameter than the end an to which latter it is securedby a screw qwhich is inserted in the aperture m The plate has a head orother projection p which engages the depression m and prevents theturning of said plate on the stem. Below the aperture Z is an aperture Zof larger diameter and screwthreaded to receive a bolt -headed screw rhaving a flange r. The disk is provided with an annular recess Z whichreceives a gasket or washer s which, when the valve is closed, restsagainst the valve seat 15. At Z the disk is cut away to leave a spacebetween the disk and the flange r in order that said flange may beardirectly against the gasket and insure a steam tight joint. By reason ofthe peculiar connection between the stem and valve proper, the stem maybe turned independently, and the plate, by reason of the arrangement ofits projection with the depression in the stem, follows the movements ofthe latter and can only be disconne'cted by hand.

The universal nature of our improved valve renders its ready applicationto any arrangement of steam supply and return pipes, and by employingremovable and interchangeable reducer or union joints, the same valvemay be used with different sized pipes,'inasmuch as joints of differingsized internal diameter may be employed. The valve is also of that typewhich permits of a circulation of steam independent of a radiator, anddispenses with the employment of two valves.

The valve is neat and attractive in appearance, is compact, and havingfew parts is not liable to disorder and leakage.

We claim as our invention-- 1. A radiator valve having inlet and returnopenings of the same diameter, and joints for let and return pipes,adapted to be turned to any angle with the valve connection to theradiator as a center, said openings being of the same diameter, andjoints for the supply and return pipes having different diameters andadapted to be interchangeably connected with said openings.

4. In combination with the radiator valve herein described, a valve stemhaving a collar above the end of the stem, a disk having an aperture toreceive freely the end of the 'stem, a plate non-revolubly but removablyconnected to said end, and a nut for closing said aperture.

5. In combination with the radiator valve herein described, a valve stemhaving near its lower end a collar, and at said end a transverse groove,a disk rotatable on the stem and having an aperture to receive said end,a plate removably secured to said end and having a head engaging thegroove, and a nut for closing said aperture.

6. In. combination with the radiator valve herein described, a valvestem having the collar, groove and threaded socket, a disk having anaperture to receive the end of the stem, said aperture having a threadedenlargement, a plate having a bead engaging the groove, a screw passedthrough the plate into the socket, a gasket in a recess in the disk anda securing nut screwed into said enlargement and holding the gasket inplace.

In testimony whereof we affix our signatures in presence oftwo-witnesses.
